.To all whom, t may concern.-

Be it known that we, GEORGE C. Locas and J OHN A. PflrrEEsoN, ofCleveland, in the county of Cuyahoga and State of Ohio, have inventedcertain new and useful Improvements in Filling for Railroad-Frogs, Ste.;and we do hereby declare the following' to be afull, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to made and use the same.

Our invention relates to improvements in rolled filling for railroadfrogs, crossings, &e.; and it consists in certain features ofconstruetion and in combination of parts that are hereinafter described,and pointed out in the claims.

The object of our invention is to provide a light, strong, cheap,durable, and elastic filling that can be rolled so nearly into therequired shape that no fitting-such as planing, chipping, or filing-willbe required, and that will, when in place, render the structure in whichit is used sufficiently elastic that it can conform somewhat to the bedthat supports it. Heretofore cast-iron has been much used for thispurpose, but it makes a frog or other structure too rigid, so that whenheavy loads are passing over, if the bed has settled in any part and isout of line, the bolts of the structure are liable to be broken. Thereare wroughtiron fillings used that are made in pieces to render themless rigid, but theselare too expensive.

In the drawings, Figure 1 is a plan view of a railroad-frog in which isshown our new lilling. Fig. 2 is a cross-seetion taken on the line of aa, Fig. l. Fig. 3 is a cross-secti0n taken on the line of b b, Fig. l.Fig. et is a cross-section taken on the line c c, Fig. 1. Fig. 5 is across-section taken on the line d d, Fig. l.

A represents the filling, made of wrought steel or iron, rolled in therequired shape that is shown by the section views in Figs. 2, 3, 4., and5. It will be seen, as in Figs. 5 and 6, where the parts of the lillingare lettered, that there are two heads or flanges, n, connected by aweb, n. The heads, as are shown, are of a size and shape to t the sidesof the raihwhile the web is sufficiently thin to render the fillingslightly elastic...

The filling may be heated and pressed in forms to bend it to therequired shape, and at the same time parts of the web may be upset, soas to bring the rails nearer together at certain points when it isrequired, as shown in Fig. 4.

The usual manner of fastening frogs and similar structures together isby the crossbolts g, that, as are shown, extend through the entirestructure. The bolts being usually thicker than the web, the web issevered by drilling holes for the bolts. Sometimes, however, it isdesirable to use short bolts, and in some cases holes are cut in thefilling,as shown at .I in Fig. (i.

Frogs and other structures made with this filling are sufficientlyflexible and elastic so that in ease the bed, that is usually of ties,is out of line the frog or other structure will give or spring a littleto accommodate itself' to the bed without breaking the bolts.

rlhe filling is made with the web in the center or otherwise, butpreferably below the center, as shown, to give more room for theflangesl of the car-wheels.

The filling is usually rolled out in long lengths and then cut in piecesof any desired length.

Vhile in the foregoing description we have shown the manner ofconstructing frogs with our new iiller,we do not limit ourselves to itsuse in frogs alone, as it is equally suitable in all places when two ormore rails are required to be blocked apart and held adjacent to eachother. l

What we claim is- 1. As a filler for railroad frogs, crossings, andother similar purposes, wrought iron or steel bars rolled in the shapedescribed, substantially as shown, and for the purpose set forth.

2. As a filler for railroad frogs, crossings, and other similarpurposes, wrought iron or steel bars rolled in the desired shape,consisting of two heads or flanges adapted to fit the sides of the railsand connected by a web sufficiently thin to be slightly elastic undersuch pressure as would usually be brought to bear by passing trains,substantially as and for the purpose set forth.

3. As a iiller for railroad frogs, crossings, 10o

and. other similar purposes, wrought iron or steel bars rolled into theproper shape, consisting of two heads or ilanges adapted to frt thesides of rails and connected by a thinner porthe required shape anddimensions without planing, chipping7 filing, or other similar flt- 15ting, substantiallyT as and for the purpose set forth.

In testimony whereof we have signed this speoieation inthe presence oftwo subscribing witnesses.
